SPECIFICATION forming part ef Lettere Patent No. 607,706, dated Jely 19, 189s.

Application filed November 19, 1897. Serial No. 659,131. (No model.)

To all whom t may concern.-

Be it known that I, CLAYTON MILLARD RICHARDSON, of the city of Toronto, in the county of York, Province of Ontario, formerly of XVinnipeg, in the county of Selkirk, Province of Manitoba, Dominion of Canada, have'invented a new and VImproved Heating- Drum, of which the following is a full, clear, and exact description.

My invention relates to an improvement in heating-drums, and has for its object to provide a device capable of being used in the same apartment with a stove, furnace, or other heater or in an apartment removed therefrom, the drum being so constructed that it may be large or small, as desired, and Whereby also the drum will afford amaximum of heat and without interfering with the draft of the heater to any appreciable extent.

A further object of the invention is to construct the heating-drum in sections, which sections may be expeditiously disconnected or assembled, enabling the various sections to be readily cleaned lor 'repaired when necessary.

A further object of the invention is to so construct the drum that radiant heat will be obtained from the waste products of combustion, and in addition the waste products of combustion will be made to heat lues or pipes through which fresh air constantlyT passes.

The invention consists in the novel construction and combination of the vseveral parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a Vertical section through the drum, taken on the line 1 1 of Fig. 3. Fig. 2 is a vertical section through the drum, taken parallel with the section shown in Fig. l on the line .2 2 of Fig. 3. Fig. 3 is a plan vieW of the drum, a portion of the top of the upper section being broken away. Fig. 4 is a plan view of the second section of the drum. Fig. 5 is a transverse section on the line 5 5 of Fig. 1. Fig. 6 is a transverse section on the line G G of Fig. 1. Fig. 7 is a transverse section on the line 7 '7 of Fig. 1; and Fig. 8

is a side elevation of the improved heatingdrum, illustrating the manner of connecting the same With a straight pipe.

The drum may be made of any number of sections. In the drawings four sections are shown as connected together, designated, re-` spectively, as A, B, C, and D..

. The upper section A of the drum is divided into two compartments ct and ct' bya central Vertical partition 10, and a pipe 11, adapted for connection with the heater or other source of heat-supply, leads into the compartment a. An opening 12 is made in the partition 10, which opening is normally closed by a Valve or a damper 13, usually mounted to slide on the partition and provided with a handle which extends out through said section of the drum. An offtake-pipe 14 for the Waste products of combustion is carried through the top of the section A into the compartment Ct of the same, and the oiftake-pipe 14 is surrounded by a second pipe 15, which isin the nature of a cut-off valve, being provided With a suitable handle, and when it is desired to retain the products of combustion in the drum this cut-off Valve is carried downward to an engagement with the bottom of the upper section, as shown in dotted lines in Fig. 2. In the bottom of the compartment a, at the corner farthest removed from the inlet-pipe 11, an opening 17'-a is made, surrounded by a collar 17, and in the corner of the compartment ct diagonally opposite the corner in Which the opening 17 is made an opening 1Gn is produced in the bottom of the said compartment a', as shown in Fig. 2, which is surrounded by a collar 16. f

The second -section B of the drum is provided with a vertical central partition 18, dividing the said section into two compartments b and b. In the top of the compartment b an opening 19a is made, surrounded by a collar 19, adapted to fit around the collar 17 of the compartment ot of the upper drum-sec- Jtion, and in the top of the compartment bof the second drum-section an opening 2OCL is made, inwhich a sleeve 20 is secured, the sleeve being adapted to enter the collar 16 of the upper drum-section, establishing communication with the compartment a of the same. An air-pipe 21 is passed through the second drum-section from the top through the IOO IOl

bottom, and in the bottom of the compartment b ofthe second drum-section an opening 22a is made, surrounded by a collar 22, and a similar opening 23a is made in the bottom of the compartment b of the second drumsection, surrounded bya collar 23, preferably made in two diameters.

The third drum-section C is divided by a partition 24 into two compartments c and c. In the top of the compartment C an opening 25 is made, surrounded by a collar 25, which is passed over thecollar 22 of the next section above, and a pipe 26 extends through the compartment c from top to bottom, connecting with the pipe 2l of the second drum-section B. In the bottom of the compartment o of the third drum-section, at the corner diagonally opposite to that in which the opening 25"L is made, an opening 27a is produced, surrounded by a collar 27, as shown in Fig. l, and in the top of the compartment e an opening 28 is made, which receives the sleeve or collar 23, projected downward from the second drum-sectlion B, as shown in Fig. 2. A second air-pipe 29 is made to pass through this compartment c', and in the bottom of the third drum-section C an opening 30a is made, surrounded by a downwardly-extending collar 30, which collar is in two diameters, being similarly made to the collar or sleeve 23.

' The lower drum-section D is divided into an upper compartment d and a lower compartment CZ' bya horizontal partition 33. In the top of the upper compartment d an opening 3l is made, surrounded by a collar 32, which receives the collar 27 of t-he third drumsection C, and a jacket 34, which is in the nature of a vertical partition, extends through an opening in the top of the compartment d through the partition 33. 'Iwo pipes 36 and 37 are carried from the bottom 35 upward through the jacket 34 and beyond the top of the lower section D to a connection, respectively, with the pipes 26 and 29 of the third drum-section C. The pipes 36 and 37 are open at the bottom and the top. The bottom 35 of the lower compartment d is provided with a number of apertures or openings 38.

` In operation the products of combustion enter the compartment a ot the upper section of the drum, pass down through the openings 17 and 19L into the compartment b of the second section, thence through the openings 25 and 22a into the compartment c of the third section, and through the openings 27 and 3l into the upper compartment d of the lower drum-section. The products of combustion then pass up through the collar 30, which enters the compartment d, and the products of combustion will ascend through the opening 30a into the compartment e of the third drumsection, then through the opening 23a into the compartment b of the second drum-section and through the openings 2Oa and 16a in the compartment ct of the upper drum-section, and from thence out through the ofttake-pipe 1 4. The hot air in its circuit through the form pockets at their inner ends, which absolutely prevent the hottest of the products of combustion from passing into the flue.

In Fig. 8 I have shown a means of connecting the heating-drum with a straight supplypipe 39, accomplished by what I term a double T. One lateral member 40 of the said T connects with the outlet-pipe 14 of the drum, and the other lateral member 4l of the double T enters the intake or receiving portion ot' the upper drum-section A. Two dampers 42 and 43 are located between the two lateral members 40 and 4l. The dampers are principally intended to direct the products of combustion into the heater. Both dampers are solid and when closed a dead-air space is between-them, eectually preventing the heat from passing from the suppl r-pipe to the flue.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a heating-drum,the combination,with a series ot sections, and means, substantially as described, for introducing heat into the upper section of the drum and conducting it to the lower sections, of return-pipes for the heated air and connecting said sections, each return-pipe from an upper section extending within the next lower section, forming a pocket, and an outlet-pipe having a pocketsection within the upper drum -section, as specified.

2. A heating-drum comprising a series of compartments arranged one above the other and connected together, the compartments with the exception of the lower compartment being divided into subcompartments by vertical partitions,one of which is provided with a valve, the lower compartment being provided with a partition extending only partially across the same, substantially as described.

3. A heating-drum comprising a series of compartments one above the other and connected together, the compartments being divided into subcompartments by vertical partitions with the exception of the lower compartment, and air-pipes extending through the lower compartment and through the next compartment above, said air-pipes having their outlets between compartments so as to discharge heated air under the bottom of compartments, substantially as described.
